Application filed May 19,1905. Serial No. 261,157.

T0 at whom it may concern:

Be it known that I, CONRAD HUBERT, a citizen of the United States, residing at the borough of Manhattan, city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Portable Electric Lights, of which .the following is a specification, reference being had therein to the accompanying drawings, forming a part thereof.

effort on the part of the operator.

I will now describe the portable electric lights illustrated in the accompanying drawcircuit-closer.

ings and embodying my invention and will thereafter point out my invention in claims.

Figure 1 is a front elevation, partly in section. Fig. 2 is a top or plan view with the circuit-closer in open position. Fig. 3 is a similar view showing the circuit-closer in closed position. Fig. 4 is a plan view of the battery detached. Fig. 5 is an underneath plan View or view looking upward with the battery and bottom plate of the casing removed. Fig. 6 is a front elevation, partly in section, of a modified construction of the Fig. Tie a top or plan view of the same. Fig. 8 is an underneath pi'an view of the same with the battery and bot-v tom plate of the casing removed. Fig. 9 is a plan view of another-modified construction.

The casing is shaped to form a thin flat package without angular corners or protuerances, so as to be well adapted to be carried in the pocket of the user. The body a of the casing is made of either a conductive or non-conductive material and if of metal preferably'has a suitable covering, as shown, and the casing is wide at the. flat sides and I semicylindrical at the thin sides, so as to 3, 6, 7, and 8 the cover I) at the upper end of the casing is fixed upon the casing, while the lower cover 0 is partly removable and.

includes a sliding cover-plate e, sliding in grooves provided on a collar 0, the collar 0 being permanently fitted on the lower end of the casing.

In the construction shown in Fig.9 the cover at the upper end of the casing includes a sliding cover-plate g, which slides in the collar 0, permanently fitted on the upper end of the casing.

The battery 7 is composed of a plurality of cells arranged side by side and suitably fastened together and covered so as to make a single package, which may be readily removed when the battery is exhausted and replaced by a new battery made up in a similar package. The contact-terminals of this battery are two metallic strips 8 and t,

the strip it being of considerable length and extending over the battery a sufficient distance to contact with the, projecting terminal lot the lamp and the other contactstrip 8 extending upward in suitable position to coact with the circuit-closer.

The lighting element consists of a miniature electric light j, which is threaded in a metallic socket is and which carries at its lower end a terminal Z. This lamp-socket is sha ed like an inverted dome, and its inner wall is provided with a reflecting-surface such that as a result of its concave shape the socket also serves as a owerl'ul light-reflector. The upper portion of t is lamp-socket 7c flares outwaid and rests upon the top of a threaded. ring-s aped neck a, which rojects upward above the upper cover I). A ens 0 rests upon the upper face of the flaring portion of the socket, and a threaded clamping-ring p is secured over the threaded neck a and clamps the lens and reflector in place.

In the constructions shown in Figs. 6, 7, and 8 the projecting threaded neck n is a part of the cover and may be integral therewith. In the construction shown in Figs. 1, 2, 3, and 5- this threaded neck projects upward from and may be, as shown, integral with a sliding plate g, which is fitted to slide against the under or inner face of the top portion of the upper cover I), an elongated opening being IE is in its extreme sliding plate 9 also carries an inwardly-proj ectingcontact-piece u, which coacts with the contact strip or terminal 8, projecting upward from the battery. This movable lampcarrying part is the circuit-closer, and when position to the right, as shown in Figs. 1, 2, and 5, the contacts a and s are separated and the circuit open, and when it is in its extreme position to the left, as shown in Fig. 3, the contacts are together and the circuit is closed.

In the construction shown in Figs. 6 to 8, inclusive, the projecting threaded neck carrying the lens, lamp-socket, and lamp is stationary, and a separate slidable part is pro vided for closing the circuit, this separate slidable part comprising the sliding button w, the head of which slides upon the top of the upper cover and the shank of which protrudes through an elongated opening in the top of the upper cover and is secured to an inner sliding plate 2., which is guided between strips '1 'u on the inner face of the top of the cover, and which carries a contact-piece u, shown as bent d own therefrom and projecting to the left in suitable position to coact with the contact-strip s of the battery. This movable part is a circuit-closer and is actuated by pushing the button in to the right or the left, its movement to the left carrying its contactpiece into circuit-closing position and its movement to the right opening the circuit.

in the construction shown in Fig. 9 the projecting threaded ring is also stationary relative to and may be integral with the cover-plate 9; but this cover-plate, as above described, is slidable as a whole. .The contact-piece 11?, carried by this upper sliding cover-plate g is moved into contact with the battery-terminal s when the cover-plate g is moved to the left, as shown in. Fig. 9, and is lamp-carrying moved into circuit-opening position when the cover-plate is moved to the right.

it will be noted that one of the terminals of the battery, the contactstrip t, is at all times in contact with the projecting terminal Z of the lamp. This contact is made when the battery is inserted into the casing and the spring resistance of the contact-strip t produces a con "tant pressure, such as will maintain a sa ti ctory contact so long as the battery and lamp are in place. The other terminal s of the battery, as above described, is brought into contact with the projecting contact-strip of the circuit-closer by an intentional act on the part of the user. In the construction shown in Figs. 1, 2, 3, and 5 this intentional act is the movement of the lens and lamp-carrying projection to the left. The circuit thus closed flows from the terminal L" of the battery to the terminal Z of the lamp, through the lamp and to the conductlve s eevc thereof, and through the socket and contact u to the terminal 8 of the bat- I tery. in the other constructions shoWn the circuit is closed in a similar manner; but in the construction shown in Figs. 6, 7, and 8 the sliding button w is actuated to open and close the circuit, while in the construction shown in Fig. 9, as in the first construction shown, the circuit-closing operation is performed by moving the projecting lens and part to the left; but in'this instance the entire top plate of the casing is moved with the projecting part in the circuitclosing operation.

It is oesirable that the movable circuitclosershould be movable only by intentional operation, and therefore the sliding parts are fitted with sufficient tightness to assure their maintenance of the positions to which they have been intentionally moved. They will therefore hold the circuit in closed conr. ition without effort on the part of the operator to maintain that condition.

It is to be noted that in the constructions above described, in which the lamp-carrying part is movable, the lamp-terminal Z is caused to rub over the contact-strip t'ofthe battery during each circuit-closing and circuit-o ening operation, and thus each operation of the circuit-closer tends to rub these contacts and keep them clean. The other contacts are also kept inclean condition by their ordinary operation by reason of their spring resistance and wiping action of the contacts.

It is obvious that various other modifica tions may be made in the constructions shown and above particularly described. within the principle and scope of my invention.
